# I’m unable to see the Cancel e-Invoice option for the transactions pushed to the IRP. What should I do?

The **Cancel e-Invoice** option will be visible only for 24 hours after the IRN is generated for the transaction. After 24 hours, the Cancel e-Invoice option will be replaced by the **Mark as Cancelled** option.

You can find the date and time when the IRN was generated from the **Ack Date** field located at the footer for the transaction’s PDF. Here’s how:

*   Go to the _Sales_ module on the left sidebar and
    *   Select **Invoices** if the transaction is an e-invoice or debit note
    *   Select **Credit Notes** if the transaction is a credit note.
*   Select the transaction for which you want to view the Ack Date.
*   On the Details page of the transaction, scroll down to the footer of the transaction’s PDF.

The **Ack Date** field at the footer of the transaction’s PDF will contain the date and time when the IRN was generated for the transaction.
